form of apparatus to have the covers ofthe .compartments provided Qwith throughfwhieh a direct draftcan befesta lished, if desired, .and it is also desirable in 'practice to have the covers removable and at .the same time toso vconstruct them that as i vfar. as possiblellossof heat by lradiation and convectionwill be' prevented.

onefor each compartment,' which are constructed substantially alike, similar parts being similarly lettered,

andthe variations. therein will be hereinar'terv pointedout. Each of thesev covers has a eentral opening d, the Wall of which is 'preferably formed by a cylinder d', of metal, on the upper portion of which'is a flange d?, which slfipports the cylinder upon the to plate d o t e c over, vwhich' plate dais pre erably of wood, and the ou-ter edges of the lates d3 of covers D and-D2. are extended su iciently to cover the adjacent top edges of the sides and -end of the casing A and sup ort the cover -t hereon,as indicated-in the rawi'ngs. The

top plate of theintermediatecover D simply extendsover the adjacent to edges of the side portions..o fthe casin thecovers may lbe bracedy' as shown. f

, The covers are preferably bniltup below ythe plateda f abottom plate d of metal', su-

perimposed layers of asbestos Z7 or other non-heat-conducting material, la layer of` metald, which may be su erimposed by a ich and the top ,v he' corners ofare additional layers of'asbestosor.`

relative size ofthe opening and the covers is not a feature of the invention.

.The adjacent edges of the covers abut very closely, as shown in Fig. I2, and-afterthe coversare in laterally- "through the upper end walls of the casin and bearing agalnst metal plates'e-, attache to the end eoversZ as shown in thedrawings. By this meanstlght joints are formed between intermediate sections.l The weight of place they may be pressed together the covers will be suiiicient to .keep t ern' ges prlperly tight, and the Vo verhanging -e an portions-of thecovers resting upon side the u peredges of the casing will form lsii-iiir tight joints to prevent any material cient y. 'loss of heat or gases. The covers may also rest'upon packed gasketsc on the upper edges 'of the partitions C, as indicated in.

tween the covers and the, tops of the partitions, so as to prevent passage of vapors on odors from one compartment to the other over the partitions. Preferably each cylinder d is provided with a shoulder 112 near its upper end, upon which may be supported nested lids F. Above these lids yand closing the open end of the cylinder isa removable plate G, provided with an opening closed by a valve g.y Each of the cylinders in the several covers may be rovided with such de vices. When both t e lids and cover-plates are in position and the valves closed, there will be practically no chance for heat orgases to escape from. the-compartment. If it is desired to produce a circulation of gases through either compartment orto reduce the temperature in any compartment for any reason, the valve gthereof can be partly opened and oiielid F removed, thereby providing a direct vent-passage of any desired size.

If desired, the covers G may be removed and one ormore lids F removed and a culinary vessel (indicated at V in the drawings) I may be supported upon the lids and heated by direct heat from lthe compartment. The covers may also be provided With tubes H,

extending 4 into l the compartments provided y with removable caps 71., and through these tubes pyrometers may be introduced into the compartments to determine the temperature therein. Each cover may also be provided with handles D3, by which it can be removed and replaced.4

By the means described the gases deliv-` -ered into the compartments 1 2l 3 from the heater S can be retained therein and stored and accumulated in the walls thereof, or, if

it' be desired, the compartments may be kept e at different tem eratures by meansV of valves g, or, if' esired, cooking can be accomplished in some compartments by stored heat, while live heat is being introduced into 'oi covers each having top plates adapted to overreach and rest upon the adjacent top edges of the chamber.- walls and provided with openings, and removable closures for said openings, said covers having non-hea tconducting walls, and means for'pressing the covers together laterally when in position.

3. The combination of a heatingchamber having a series of compartments, a top for each compartment provided with an opening surrounded by a metal cylinder, lid-supports in said cylinder and a removable cover provided with a valve-opening closing the upper end of the cylinder.

4., The combination of a heat-storing chamber, having an o en top, a series of vertical partitions in sai chamber, a cover for each compartment, said covers together forming the top of the chamber and cach having extending portions adapted to "rest upon the upper edges of the sides and the two end covers also ,having extending portions adapted to rest upon the adjacent end walls 'of the chamber, and having interior nonheat-conducting layers.

5 The combination of a heatstor1ng lchamber having an open upper end, a series of vertical partitions in said chamber having gaskets on their upper edges, a cover for each compartment, said covers together forming the top of the chamber and each having extending upon the upper e ges of the sides and the two end coversal'so having extending portions ada ted to rest upon the adjacent end wallsof t 1e chamber, said covers also resting u on'the gaskets on top of the partitions to c ose the compartments.

6. The combination of a heat-storing chamber, having an openupper end, a series ,of vertical partitions in said chamber, a series of covers, one for-each compartment, to-

gether forming the top of the chamber and each having extending portions ada ted to rest upon the upper edges of the si es and the two end covers also having extending portions adapted to rest upon the adjacent end walls of the chamber and also having interior non-heatconductinglayers, each cover having an opening, lids supported in such o ening, and a closure for the opening above t 1e lids. y
